Ukuzalwa kwentsimbi engagqwaliyo kunokulandelwa emva kowe-1913, xa ingcali yesinyithi yaseJamani uHarris Krauss yafumanisa okokuqala ukuba intsimbi equlethe i-chromium inokumelana nokugqwala okugqwesileyo. Olu kufunyanwa lwabeka isiseko sentsimbi engagqwaliyo. "Intsimbi engagqwaliyo" yokuqala ikakhulu yintsimbi ye-chromium, esetyenziswa kakhulu kwiimela nakwizitya zokutya. Ngeminyaka yoo-1920, ukusetyenziswa kwentsimbi engagqwaliyo kwaqala ukwanda. Ngokunyuka komxholo we-chromium kunye ne-nickel, ukumelana nokugqwala kunye namandla entsimbi engagqwali kuye kwaphucuka kakhulu. Itekhnoloji yemveliso yeimibhobho yentsimbi engagqwaliyoivuthwa kancinci kancinci kwaye iqalile ukusetyenziswa kumashishini eekhemikhali, ipetroli kunye nokulungisa ukutya.
Iipayipi zentsimbi engagqwaliyo zisetyenziswa kakhulu kwishishini lokwakha ukuxhasa ulwakhiwo, ukuhombisa udonga lwangaphandle,izibonda kunye nee-handrailsNgenxa yokumelana kwayo nokugqwala okuhle kakhulu kunye nenkangeleko yayo entle, iipayipi zentsimbi engagqwaliyo zifanelekile ngokukodwa ukusetyenziswa kwiindawo zangaphandle kunye nemozulu yaselwandle. Ayikwazi nje kuphela ukumelana novavanyo lwemozulu embi, kodwa ikwanciphisa nesidingo sokugcinwa, okwenza isakhiwo sihlale ixesha elide kwaye sibe sihle.
Ngophuhliso lwesayensi netekhnoloji, itekhnoloji yeepayipi zentsimbi engagqwaliyo iyaqhubeka nokuphucuka, kwaye kuye kwavela ezinye ii-alloys ezisebenza kakuhle, ezifanaimibhobho yentsimbi engagqwaliyo, imibhobho yentsimbi engagqwaliyo ephindwe kabini njalo njalo. Ezi zinto zintsha ziyahlangabezana neemfuno zoshishino ezifuna kakhulu kwaye zikhuthaza ukusetyenziswa kwemibhobho yentsimbi engagqwaliyo kwiindawo ezininzi. Uphuhliso lwexesha elizayo luya kuqhubeka lugxile ekuphuculeni iipropati zezinto kunye neenkqubo zemveliso ukuze ziphendule kwiimeko ezinzima zokusetyenziswa kunye neemfuno zemarike.
Amashishini eekhemikhali namayeza asebenzisa iityhubhu zentsimbi engagqwaliyo ukuthutha iikhemikhali namayeza kunye nokuphatha iintlobo ngeentlobo zolwelo olubolayo. Udonga olungaphakathi oluthambileyo lombhobho wentsimbi engagqwaliyo alunciphisi nje kuphela ungcoliseko lolwelo kwinkqubo yokuthutha, kodwa lukwanceda ukucoca kunye nokubulala iintsholongwane, ukuqinisekisa ucoceko lwenkqubo yemveliso kunye nokhuseleko lwemveliso.
Kwishishini lokutya neziselo, iityhubhu zentsimbi engagqwaliyo zisetyenziselwa ukucubungula ukutya, ukuhambisa iziselo kunye nokupakisha. Iipropati zayo ezingenabungozi, ezimelana nokugqwala kwaye kulula ukuzicoca ziyahambelanaiimfuneko zokutya, ukuqinisekisa ukhuseleko lokutya kunye nococeko lwenkqubo yemveliso. Ukongeza, ukuqina kweetyhubhu zentsimbi engagqwaliyo kunceda ukunciphisa amaxesha okugcinwa nokutshintshwa kwezixhobo.
